CROSSBOW.

SPECIFICATION forming part of Letters Patent No. 577,641, dated February23, 1897.

Application filed July 7,1896.

To all whom it may concern:

Be it known that I, GUsrAv BRUDER, a citizen of the United States,residing at Annapolis, in the county of Anne Arundel and State ofMaryland, have invented certain new and useful Improvements inCrossbows; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to improvements in crossbows, the inventionresiding particularly in the detent for holding thebow-string in itsrearward position and in the means for releasing the same.

The invention consists of a crossbow having the usual stock and barrel,a bow proper secured in the outer end of the barrel, a bowstring, and adetent mechanism consisting of a disk having a shoulder thereon which isadapted to engage the bow-string, a spring for normally urging said diskto its rearward position, and a trigger engaging a second shoulder onsaid disk.

The invention also consists in other details of construction andcombinations of parts, which will be hereinafter more fully describedand claimed.

In the drawings forming part of this specification, Figure 1 representsa perspective view of my device. Fig. 2 is a vertical longitudinalsection. Fig. 3 is a detail view of the detent-disk. Fig. 4 is a similarview of the trigger.

Like reference-numerals indicate like parts in the diiferent views.

The crossbow is made up of the stock 1, the barrel 2, having alongitudinal groove or recess 3 upon its upper surface, the bow 4L, andthe string 5. A slot 6 is formed in the stock 1, and in the slot ispivoted a detentdisk 7, having a shoulder 8 upon its upper surface whichthe bow-string 5 is adapted to engage, and a shoulder 9, just beneaththe shoulder 8, against which the upper end of the trigger 10 is adaptedto hear. The disk 7 is pivoted upona shaft 11, which has a coilspring 12secured to it, one end of which engages the disk 7 and tends to hold itnormally The trigger 10 has a in its raised position.

$erial No. 598,301. (No model.)

shoulder 13 upon its rear side, which is engaged by arm of a coil-spring14, secured upon a pin 15, to urge the lower end of said triggerforwardly and the upper end thereof rearwardly into engagement with theshoulder 9.

The normal position of the parts is as shown in Fig. 1, with the disk 7in its raised position and. the upper end of the trigger 10 engaging theshoulder 9 thereon. The said disk is now held from rotation, and bywithdrawing the bow-string 5 the same may be slipped behind the shoulder8 and held in such. position until it is desired to operate the device.

A slug or dart is then inserted at the rear lend of the groove 3 and thetrigger 10 com- I pressed. WVhen this is done, the upper end of saidtrigger is thrown out of engagement with the shoulder 9, and thepressure of the bow-string 5 is sufficient to move the detentdisk 7forwardly upon its pivot, propelling the slug or dart forwardly from thebow. As soon as the string has slipped from the shoulder 8 the detent 7is thrown back into its normal position by the spring 12, and when thetrigger 10 is released the same is thrown into its normal position bythe spring 14:. The parts are therefore always in operative position.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In a crossbow, the combination with the stock thereof having a slottherein, the bow proper and the string thereof, of a detent-diskpivotally mounted in said slot having a shoulder at one point thereonwith which said bowstring is adapted to engage, a spring for nor-'-mally holding said disk in its rearward position, and apivotally-mounted trigger whose upper end is adapted to engage a secondshoulder on said disk, substantially as and for the purpose described.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
